IMPROVEMENT IN SIOKE-SHAVES.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, SETE' T. HU'ICIXINS, of North Anson, in the countyof Somersen'and State of Maine, have invented a. new and usefulImprovement in Heel or VSpoke-Shaves; and IV do hereby declare thesameto be fully described in' the following specification, andrepresented in the accompanying drawings, of which- Figure 1 is a topview,

Figure 2 a bottom view, and

Figure 3 a. side elevation of a spoke or heel-shave provided with myimprovement.

In carrying out my invention, I not only make the adjustablethroat-piece or gauge separate from two buttresses, so applied to thestock as to be capable of being moved or adjusted thereon, in order toproperly adjust the throat-piece relatively to the knife or cutter, butI hinge the throat-piece to one ofthe said buttresses in a manner toenable the throat-piece to be turned aside or away from the knife, inorder to allow the latter to be sharpened, as occasion may require; theadjusting abutments of the throat-piece remaining in the mean whileundisturbed in their positions relatively tothe steek. After thesharpening of the knife may have been effected, the restoration ofthe-throat-piece to place against the abutment, away from which it wasmoved, can bev accomplished, by simply turning the throat-piece downthereupon.

In the drawings, A denotes the stock, made in the usu'al form, andhaving two handles a a.' B is the knifor cutter, fastened. in or to thestock, C is the gauge, and D E its' two adjustable'abutments, each ofthe latter being held to the stock by means of a clamp'screw, b, goingthrough a slot made in such abutment; the same being so as to enable thedistance of the gauge or throatpieee C from the cutting-edge of theknife to be either increased or diminished, as circumstances mayrequire. The gauge C is hinged, at or near one extremity, to theabutment E, and at its other endit bears against the other abutment,which is formed with a shoulder or bearing-surface for the gauge to reston. This application of the gauge enables it to be moved from the abutmeut D into the position denoted by the dotted lines at C in fig. 3.

I do not claim merely applying the gauge to the stock, so as to beadjustable or capable of being'adj usted nearer to or further from theknife, in order to either increase or diminish the chip-throat orpassage between the knife and the gauge; but

I. I do claim the combination of the separate abutmcnts D E, applied tothe stock A, so as to be adjustable, in manner as described, with thegauge G hinged to one of such iabutments, and being separat-e from theother, and to operate with respect to it substantially as explained. i

, 2. I also claim the application of the gauge to its adjusting-devices,so as to he removable from them or either of them, and the knife, whenthc means of the adjustment of the gauge is held stationary relativelyto the stock, as described. l
